Integrated Broom Scraper Blade for Heavy-Duty Surface Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broom scraper attachments are not strong enough for heavy industrial use and can cause damage to surfaces due to exposed side edges.
Innovation Solution
A broom design with an integrated scraper blade where the blade is partially enclosed within a recess in the head, secured by protrusions and holes, and embedded within the head material to enhance strength and prevent damage, allowing the scraper to be used effectively without separate devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate blade device is fixed to the broom above the head near the handle, then the scraper can be used by inverting the broom head, but the blade construction is not particularly strong and not suitable for heavy industrial use
Solution Approach 1:
The scraper blade is merged with the broom head to form an integrated unit. The blade is positioned within the head structure itself, making it an inherent part of the broom rather than a separate attachment. This integration strengthens the overall construction and ensures the blade is suitable for heavy industrial use while maintaining scraper functionality.
2Ease of operation
If the scraper blade is a flat metal blade extending along the width of the broom head, then it can perform scraping function, but the exposed side edges can contact surfaces such as nearby walls and cause damage
Solution Approach 1:
The scraper blade is nested within the head structure, with its side edges enclosed by the head material. This nesting arrangement protects the blade edges from contacting and damaging nearby surfaces like walls, while still allowing the blade to perform its scraping function effectively.
3Object-affected harmful factors
If the scraper blade is enclosed within the head structure, then surface damage is prevented, but the blade needs secure attachment mechanisms
Solution Approach 1:
The attachment features (protrusions and holes) are built into the blade and head structure during manufacturing, rather than requiring separate attachment steps. The protrusions on the blade align with corresponding holes in the head, creating a self-aligning, pre-configured attachment system that secures the blade firmly while maintaining a relatively simple overall structure.

AI summary
A broom (10) comprising a head (12) and a handle (14). The head (12) comprises a first portion (16) having a plurality of bristles and a second portion (17) extending outwardly from the first portion (16) at an angle thereto. A recess (28) extends from adjacent a first end of the second portion (17) to adjacent a second end of the second portion (17) and a scraper blade (30) is fixed at least partially within the recess (28) such that at least portions of longitudinal ends of the scraper blade (30) are covered.
